I am starting to look at the query optimizer in SQL server 2008 and I’m particularly interested in the statistics profile that can be shown for a query. So far i understand that the result shown for the statistics profile is based on the statistics stored in开发者_如何学Go SQL server and not the results from executing the query (e.g., the ‘Rows’ column), right?

Now, is there a way to get the result from the statistics profile without executing the actual query at the same time?


SET STATISTICS_PROFILE ON returns both actual and estimated row counts.

If you want just estimated row counts without running the query use SET SHOWPLAN_ALL ON or SET SHOWPLAN_XML ON
